AI Workplace Occupancy Sensor PoE 868 MHz – Milesight VS121-P

The Milesight VS121-P is a professional-grade AI workplace occupancy sensor designed for accurate and fully anonymous people counting in offices, public buildings, and commercial facilities. With up to 95% counting accuracy, it enables data-driven decisions for space optimization, visitor analytics, and energy efficiency.

Embedded AI algorithms analyze movement direction, dwell time, and people flow across up to 16 customizable detection regions. Smart U-turn filtering eliminates redundant counts by excluding individuals who do not actually enter a defined area.

With a 190° horizontal and 112° vertical field of view, the sensor efficiently covers large indoor areas when ceiling-mounted between 2.5 m and 4 m.

Difference compared to the standard version:
The VS121-P includes an integrated Ethernet interface with 802.3af Power over Ethernet (PoE). This allows both power and data transmission through a single network cable, making it ideal for structured enterprise environments.

Key advantages of the VS121-P architecture include:

Stable wired data transmission

Direct integration into IP-based building management systems

Support for protocols such as BACnet/IP

Centralized power delivery via PoE switches

DI/DO interfaces and RS485 (under development) for extended automation integration

Communication is available via LoRaWAN on 868 MHz or via Ethernet. No personal image data is stored or transmitted. Detection is 100% anonymous and fully GDPR compliant.

The VS121-P is ideal for enterprises and public sector installations that require reliable wired infrastructure and deeper system integration.
